To all 2'0 7mm it may concern:

Be it known that 'I, GEORGE IV. How'ns,a citizen 'o'f the United States,residin at 'Dowagiac, county of Cass, State of lVIichigan, haveinventedcertain new and useful Improvements in Combination Solid-Fueland Gas Ranges or Cooking-Stoves, of which the following is aspecification.

combination solid fuel and gas ranges or cooking stoves. I

The main'ob-jects of this invention are:

First, to provide in a combination solid fuel and gas range or cookingstove an impro'i ed oven structi'ire which is very effectively heatedeither by solid fuel, such as coalfo'r wood or by gas.

4 Second, to provide an improved combination solid fuel and gas range orstove which may be conveniently converted from one to the other. I

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. I The invention is clearlydefined and pointed out in the claims. I I

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Fi ure I is a'detail front perspective view of a structure embodying thefeatures of'my invention, with the oven adjusted to be heated by solidfuel.

I Fig. II is a front perspective view of my improved stove adjusted toheat the oven by as.

I Fig. III is a perspective view of the base of my improved stoveshowing the support for the burner plate and burner when'not in use, thesupport being released and the burner plate in position as dischargedtherefrom. I I

Fig. IV is a perspective View of the base with the burner platesupported therein.

Fig. V is an enlarged detail vertical section one line corresponding toline 5-5 of Fig. IV, showing the-latch for the burner plate support. I I

Fig. V1 .is enlarged detail vertical section on aline corresponding toline 6-6 of Fig. V, with "the burner in position in the oven, the burnercoupling being shown in operative position by dotted lines and 1nreti'acte'd position by full lines, the operating mechanism being shownin full lines.

Fig. VII is an enlarged detail section through the'burnerand burnerplate and the gascoupling, showing the coupling in operative relation tothe burner. Th s inventlon relates to improvements in I "Fig. VIII is adetail bottom view of the air damper and its operatin connection. I Inthe drawing similar re 'erenc'e characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the'ends of the section lines.

Referring to the drawing, 1 designates the stove body generally and Qthe base which is provided with legs 3. I desire to point out that Ihave not, in the accompanying drawing, attempted to maintain therelative proportion of the parts, nor have I attempted to showstrnctural features of the'body proper nor the joints or connections'for'i t s several parts, as snch details will be readily understood bythose skilled in the art to which my invention relates. I I I The "oven4L in the structure illustrated is positionedasis "common practice. Thefirepot and ashpit are at the left hand but, as thesedetails form nopart of this invention, I have not illustrated them herein. The fluefrom "the firepotextends over the top of the oven, downwardly at 3 andunder the oven at 4:, this flue arrangement "being wellknown in the art.I I I The bottom 5 of the oven is provided with a central opening 6. Thebottom 7 of the flue has an opening '8 alined with the opening'6. An airflue 9 in the heating 'fiue'conmeets these openings 6 and I8.The'botto'm of the oven forms the top wall of the heating fine.

A the heating flue and has a vertical delivery portion 11 disposedcentrally of the air flue 9. Below the air fine is a damper box 12having damper openings 13 controlled by gas delivery pipe 10 is arrangedunder 0 the damper I l pivoted at 15. The burner 16 is mounted on theunder {side of the burner plate 17 which is removably mounted in theovenso as to supp'ortthe burner in a spaced relation to the bottom of theoven and the burner plate with its ,'edges in a spaced relation "to thewalls of the even-.-

In the structure illustrated the burner plate is supported by thearms 18which engage the shelf ledges 19 of the oven. The burner is preferablymounted for limited vertical movement, being mounted, in the structureillustrated, on the headed pins 20 which engage lugs 21 on the burner.

The burner has lugs 22 which limit its movement toward the plate. Theburner,

in the structure illustrated, has a central crossportion 23 with achamberor passage therein communicating with the chambered 'andalso theburner being loosely mounted may be lifted by and partially supported onthe coupling member, thus insuring a perfect connection and alsoaccommodating-for irregularities in manufacture and any war ing ordisplacement of the parts that mig t occur 1n use. I j V V The opening 6is provided with a removable cover or closure 28. The gas couplingmember, in the structure illustrated, is actuated by the lever 29 whichis pivoted at 30 and slotted at 31 to receive a pin 32 on the collar 33of the coupling member, the collar being threaded upon the couplingmember to provide forconvenient adjustment of the coupling member. a

The actuating lever 34 is. pivotedat 35, the pivots 30 and 35 beingpreferably mounted on the gas supply pipe 10 and connected with thelever 29 by a ball and socket connection shown conventionally at. 36.

The damper 14 is connected by the link 37 to an arm 38-on the lever 34,so that by the actuation of the lever the damper is opened and closedand also-the burner is connectedand disconnected with the gas supply. 7The gas delivery pipe 10 is, in the structure illustrated, a Bunsentube, the gas being delivered thereto by the-pipe 39 con: trolled by thevalve 40. This valve, which is located atthe rear of the stove, has anactuating shaft or rod 41 extending'to the front of the stove andprovided with a handpiece and index 42 which not only indicates when thevalye is its closed position, but also the degree of opening of thevalve. To insureconnection to the burner when the valve is opened theshaft 41 is provided with a crank 42 which engages a slot 43 in a bar44'connected at its lower end to theend of thelever 34 and slidablysupported at its upper end. With this arrangement the valve cannot beopened without the gas couranged on this rack in an inverted positionand the rack swung up to the position shown in Figs. IV and V, so thatit is entirely concealed and out of the way. A push on the latch 47,with'the foot releases the rack so that its front end drops down asshown in Fig. UT and the burner plate slides out under the base andv canbe readily picked up and shoved into the oven.

For convenience in lighting theburner I provide a pilot 48, the frontend of which projects through a flange 49 on the front ed e of theburner plate.

My improved combination solid fuel and gas stove is very efficient bothwhen used with solid fuel and when used with gas. The structure iseasily adapted forthe use of either fuel. I have illustrated anddescribed my improvements in one, form in which I have embodied the samefor the market. I have not attempted to illustrate or describe other.embodiments or adaptations as I believe the disclosure made will enablethose skilled in the art to which my invention relates to embody oradapt the same as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, isz.
